To all whom t may concern:

Be it lrnown that ll, JAMES W. Baron, a citizen of the United States, and a resident of Brooklyn, in the'county of Kings and State of New Yo-rln'have invented certain new and useful Improvements inv Elapsed- Time Recorders, of whichv the following is a specification. v

My invention'relates to elapsed time recorders. lts object is to provide new and improved means for calculating and recording elapsed time; to record elapsed times on a suitable record surface, preferably a card or equivalentdevice, by means of a record of units of denomination of time, preferably of a series of units of diterent denominations of time, printed in a straight line upon such record surface and by means of an.

elapsed time indicating mark printed in such a position opposite to the said line of units or opposite to each of the said lines of units, to indicate elapsed time between two operations; also to provide a new and improved record of elapsed time, easily legible and always presenting the same point of view to the observer; also to provide new and improved printing devices for elapsed time recording machines.

ln the drawings accompanying this speci- `caticn and forming part hereof, i have shown the preferred form of my invention and will now proceed to describe the same. Referring to the specific embodiment of my invention shown in the drawings, Figure 1 is a iront view of a machine embodying my invention in its preferred form. Fig. 2 is a vertical section thereof on the lines 2&2 ot Fig. 3. Fig. 3 is a horizontal section on the'lines 3-3 of Fig. 2. Fig. 4i is a horizontal section on the lines 1 -4 of Fig. 2. Fig. 5 is a perspective view of the left-hand half of the minute driving Wheel, Fig. 6 of the driving sprocket ot the same and Fig. 'l' ot the right-hand halt of the minute driving wheel, the latter view 'showing a part of the type carrying band. Fig. 8 is a detail section of the friction wheel and band used to prevent back-lash. Fig. 9 is a sectiontalren on the line 9 9 of Fig. 2, showing the printing pads of the various columns, 2 tor the minutes, two for .the tens of minutes, two tor'- the hours and two for the tens of hours. Fig. 10 is a detailedhori- Zontal section on the line 10--10 ot' Fig. 2. Fig. 11 is a view a card, adapted to be used in the machine, and appearing as after the first or ringing in l operation. Fig. 12 is a face view of the same card after the second or ringing out operation. Fig. 13 is a detail view of spring return for operating the handle.

The machine described herein belongs to that class of machines which do not' have identication time devices, and which therefore do not automatically calculate elapsed time. lt prints two diagrams, consisting one of a complete cycle of units of the dilferent denominations covered by the machine, the units of each denomination being printed 1n a straight line, and the other of an elapsed time indicating device printed opposite `the other diagram, one elapsed time identification device opposite each line of units, the location of such device relative to the lineof units indicating the elapsed time represented in such units of denomination. Thus in the example shown on card 156 in Figs. 11 and 12, the one diagram consists of the tourlines of units, 157 representing the tens of ho-urs, 158 the hours, 159 the tens of minutes and 160 the minutes, and the other diagram consists of the single elapsed time identication device, as shown an arrow, that of the tens 'ofhours being represented by the arrow'll, that of the hours by the arrow 162, that of' the tens of minutes by the arrow 163 and that of the minutes by the arrow 164. ln the eX- arnple there shown, the elapsed time, as appearing in Fig.v 12, is readily lapparent to the eye by the location of the different rarrows. in vthe illustration there given, the elapsed time is 96 hours and 17 minutes and approximately three-quarters of a minute. The three-quartersof a minute is indicated by the relative location of the arrow 1611.,

which is about three-quarters of the distance between the units 7 and the-units 8 of the unitsv denominations of minutes.

ln order to give a clearer idea of the operation of the machine, l will first de scribe what the operator does and the results that follow and then will describe the mechanism in detail. rlhe operator first inserts into the slot 4: his card 156 with the back 14 toward him with the heading This side out at the top. He then pulls the lever 5 forward as far as possible and releases it and. removes his ticlret from the receiver. lever 5 is automatically returned to its CTV.

place by means presently to be described. The result of this operation, which is the first operation by any workman, is shown in Fig. 11. As there shown, t-here has been printed upon the card 4 columns of figures 157, 158, 159 and 160, each column representing'the units of a separate denomination of time and each arranged in a straight and vertical line easily read by any one holding the card in the ordinary position. Column 15 7 represents the units of tens of hours, 'column 158 those of. the hours, column 159 those of the tens of minutes and 160 those of the minutes. r1`he relative location or arrangement of the units of any denomination upon the card will be dependent upon the time of operation, `as will be presently understood. Upon the completion of his work, either at the close of the day, or' at the end of his job, which may be either before the close of theday or upon any day subsequent to that upon which' the work is begun, the operator again inserts the same card and this time pulls forward the lever 6 as far as it will go and then releases it, whereupon it will automatically return to its position, as will be resently described. The result of this second operation is illustrated in F ig. 12. rllhe efl'ect of this second operation has been to print upon the same card opposite to each column of figures an elapsed time identification mark represent ing the elapsed time between .the first and second operation in the units of each denomination. These elapsed time indicating marks, as shown in Fig. 12, are the arrows 161, 162', 163 and 164, representing the elapsed times in the said denominations of time. The location of each arrow with reference to the numerals representing the units of the denomination will represent the elapsed time in that denomination ,between the two operations. Thus arrow 161 representsj90 hours, the arrow 162 six hours, the arrow 163 ten minutes and the arrow 164 seven minutes and substantially threequarters of a minute of elapsed time. rlhe total of elapsed time can thus be easily read from the card as 96 hours and 17% minutes.

1 will now proceed to explain in detail the mechanism of the machine.

1 represents the casing of the machine, 2 the clock movement, 3 the drive shaft connecting the clock movement with the other parts of the mechanism.

8 is the front of the casing of the machine containing the card slot 4, into which the card 156 is inserted.

The drive shaft 3 is provided with a universal joint 169 connecting it to shaft 51, upon the lower part of which is secured bevel gear 50 meshing with bevel gear 49 on shaft 20 and driving that shaft in accordance with the time. Fast on shaft 20 is a spur gear 18, meshing with a spur gear 17 fast to a sleeve 78 loose on shaft 19. Fast on sleeve 78 is the right-hand half 16 of the minute driving gear. Secured to this half 16 is a sprocket wheel 110 provided with sprocket teeth 21 adapted to engage holes 109 in an endless type band 22. This type band is provided with type 23 running from zero to 9 inclusive representing the minutes. Band 22 is driven continuously by the clock movement at the rate of an advance of one type each minute. Shaft 19 is stationary, being secured in the side frames 9 and 10 of the machine. The endless band 22, at it-s lower end, passes around a tension wheel, composed of wheel 32, sprocket 31 and wheel 102 loosely mounted on a short shaft 30 supported in two-arms 41 secured together by connecting rod 40 fast to each, and loosely pivoted on a stationary shaft 42 supported in side frames 9 and 10. A spring 43, connected to one of the arms 41, at 45, and

to a rod 44 running from and supported by side frames 9 and 10, tends to hold sprocket wheel 32 in its downward position, keeping band 22 taut.

57 is the left-hand half of the minute driving wheeland it and sprocket wheel 110 and the right-hand half 16 of the minute driving wheel are secured together by a vrivet 58 (Fig. 3). Sleeve 78 is provided with a cylindrical opening 113, sprocket wheel 110 with an opening 111 and 57 with an opening 112, through which passes shaft 19. Part 16, 110 and 57 form an integral structure moving together loosely on shaft 19. Endless b'and 22 is also provided with a number of elapsed time indicating marks, two of which are shown in Fig. 7, and are there numbered 114 and 115 and as there shown, are in the form of arrows. These are located opposite the initial unit of each of the series of denominations upon the band. The band is shown as containing a number of complete set of units beginning at zero and running up to and through 9. Each arrow, the elapsed time indicating marks, is opposite the zero of its series of the denomination. VThese series form a continuous series extending entirely around the band 22. l

24 represents a platen which is of suflicient h eight to cover an entire series of the ten umts and A28 represents theinkribbon and 29 a part of the card 14 opposite 'the platen. Platen 24 -is provided with a Shelf 33, upon which the card rests when fully inserted. l

Opposite the band 22 are two printing pads 2 6 and 121, vthe former mounted on a lever 25, the latter on relever loose on shaft which is held in position by collars 136 an?` 137, the latter shaft extending between and` supported by the side frames 9 and 10. The printing pad 26 is for printing the line of type representing the units it minutes, shown at the right of endless band, as viewed in Fi 7, and the printing pad 121 is for printing the elapsed time indicating marks 114, 115, et seg., shown at the left of band 22, as viewed. in Fig. 7. These printing pads are operated at different times. ,The printing pad 26 for printing the line of' units is operated at the first operation of the machine when the o-perator pulls down handle 5. The printing pad 121 for printing the elapsed time identification marks consisting of the arrows 114, 115, etc., is operated on the second operation by an operator when he pulls down handle 6, as will be presently describe-d. Endless band 22 is made of any suitable flexible material, such for instance as rubber. Accordingly, when the printing pad 26, vwhich `is opposite the line of type 23 representing the units of minutes is operated, only the units of minutes will be printed by it upon the card, and when the pad 121 is operated, at a second or later operation of the machine, only the elapsed time identification marks 114, 115, etc., will be printed upon the card. The band 22 is preferably continuously driven by the clockwork. The direction of drive is shown by the arrows in Fig. 2, being upward on the left-hand side, as viewed in that figure, and downward on the right. This brings the units of the minutes denomination 23 past the platen and printing pad in a straight line, so that they are printed upon the card in a straight line, as shown in Fig. 11. At the second operation of the machine, one time identification mark is printed opposite the previously printed line of units. As this identification mark is opposite the initial unit of the denomination,.\as shown zero, its location upon the printed card will indicate the extent to which the minute endless band 22 has been moved since the first operation, or in other words, will indicate in minutes the elapsed time between the two operations.

lt will be understood that similar endless bands, driving sprockets, tension sprockets vand printing pads are provided for each denomination of time. As shown, those for the tens of minutes consist of the righthand part 59, and left-hand part and sprocket 110 of the tens of minutes driving wheel provided with a similar endless band 81 having on the right-hand end numerals from Zero to 5 inclusive representing the tens of minutes and on the left-hand arrows opposite each zero and corresponding tension wheels composed of parts 103 and 104 and sprocket wheel 31 mounted on shaft 99; for the hours, the driving wheel composed of the parts 61, 62 and sprocket 110 together with a similar endless band 82, provided on the right-hand side with numerals from zero to 9 inclusive, representing the hours, and on the left the elapsed time indicating marks opposite the zeros consisting of arrows, and a tension wheel consisting of parts 105 and 106 and sprocket wheel 31 mounted on shaft 100; and the tens of hours driving sprocket consisting of parts 63 and 64 and sprocket 110, an endless band 83 provided with units from zero to 9 inclusive on the right-hand side representing tens of hours and on the left with arrows opposite the zeros, .and a tension wheel consisting of parts 107, 108 and sprocket 31 mounted on shaft 101.

In order to prevent back-lash, I preferably provide on the sleeve 77 of the tens ofhours driving wheel a wheel 7 5 around part 80 of the periphery of which passes a brake- 4band 76 secured at one end to a stud 116 fast in the framework and having secured at its other end, at 117, a spring 118, pivoted to a studl 119 secured to the framework. As the different driving wheels are all geared together, as will be presentlydescribed, the spring 118 of brake-band 76 exerts a gentle pressure upon the entire set of driving wheels, preventing back-lash. The different parts of each driving wheels are secured together by mea-ns of rivets 58,

as already described in reference to the minute driving wheel.

The driving wheels are all continuously driven by the clockwork. That for driving the minute wheel has been already described. The minute wheel is connected by gearing with the tens of minute wheel, the latter with the hours, and that with the tens off hour wheel so as to give a continuo-us drive in the proper' ratio. This is accomplished by means of the following mechanism. On the hub of minute wheel 57 is secured spur gear 53, which meshes with av larger spun gear 52 mounted on hub 54 loose on shaft 20. The other end of hub 54 carries the spur gear 55, which meshes with lthe large spur gear 56v fast to the tens of minutes wheel 59. The gearing between the two isf110 so arranged that one complete revolution of the minute wheel would carry the'tens wheel forward one-tenth of Vthat distance. The tens of minutes wheel is similarly geared by means of spur gear 65 meshing with spurgear 66 on hub 67, loose on shaft 20, and carrying at its other end spur wheel 68, meshing with spur wheel 69 on part 61 of the hours driving wheel. This gearing is geared 6 to 1. Thehour wheel is secured to the tens of hours wheel by a 10 to 1 gearing through spur gear 70, 71on hub 72, spur gear 73 on the hub meshing with spur gear 74 fast to tens of hours driving wheel 63.

By the above arrangement, the different endless bands are continuously advanced or moved upward, as viewed in Fig. 2, and in the proportions already stated. Accordingly, the location of the dierent lines of units, as printed on the card, will be in accordance with the time of a first operation of the machine.

As the elapsed time indicating arrows stand opposite the Zero or initial point, and as they are not printed at the first operation, but are printed at the second (the columns of units not being printed at the second operation), the location of the arrow in each column will indicate the progress that has been made in that denomination of time since the first operation. Thus in Fig. 12 the arrow 161 indicates that since the first operation, where it stood opposite to the Zero, it has moved nine full units and part of the tenth, arrow ,162 that it has moved six full units and part of the next, and so on.

Tt will be observed from the above that each line of type is moved continuously and in a straight line past the printing device or printing pads and platen. The platen 24 is made broad enough to include all of the four lines or columns and each column is provided, as is the minute column, with two printing hammers, one for the line of units and the other for the arrows or elapsed time indicating marks.

The printing'pads for the different columns are shown in Fig. 9. For the minutes, the printing pad for the line of units is 26, and for the arrows A121; for the tens of minutes, theI printing pad for the units of that denomination is 123, mounted upon lever 122, and for the arrows, 125 mounted upon lever 124; for the hours, the printing pad for the line of units of hours is 127 mounted upon lever 126 and the printing pad for the arrows is 129 mountedon lever 128, and the printing pad for the tens vof hours. line of units is 131 mounted upon lever 130 and the printing pad for the arrows of that denomination is 133 mounted upon lever 132. These are all loose on shaft 34 and held in position by collars 134andv ing part of levers 25, 122, 126 and 130 respectively connected with the respective printing pads for the units of time of the different denominations 26, 123, 127 and .131 respectively. As shaft 11 is rocked, the

'projections 79, 151, 153 and 155 strike against rollers 39, 138, 142 and 146 mounted on the corresponding projections of their respective printing pads and throw the printing pads forward to the right, as viewed in Fig. 2, against the' card, ink ribincassa bon, the units of type of that denomination on the respective endless bands, forcingthem against platen 24 and printing in straight lines the units of the different denominations, as shown in Fig. 11. At a second operation of the machine, the operator pulls down handle 6. i This is mounted on shaft 12, which carries fast to it a series of projections 80, 150, 152, 154, which stand opposite to rollers 48, 140, 144 and 148 loosely secured in projections 46, 141, 145 and 149 from levers 120, 124, 128 and 132 carrying respectively the printing pads for thev arrows 121, 125, 129 and 133 respectively. This causes the arrows to be printed upon the card, as shown in Fig. 12.

As the endless bands are made of suitable HeXible material, preferably rubber, the blow of any one of the printing hammers on one-half of the endless band prints upon the card only the representation of the type on the corresponding half of the band. Thus when one series of printing devices or pads are operated, the rows of units are printed in a straight line upon the card and when the other series'of printing hammers are operated, the arrows are printed upon the card opposite the respective rows of units of the dierent denominations. Tn my device, T

lhave shown the record surface as a card,

although of course it will be understood that any suitable record surface may be employed for the purpose.

Thetension lWheels for the endless'ban'ds are all constructed as already described for the minutes tension wheel. Each is composed of two halves and a sprocket wheel riveted together and loosely supported upon a stud carried in swinging arms pivoted on stationary shaft 42. For the minutes, the tension wheel consists of parts 32 and 102 and sprocket wheel 31 fast on short shaft 30, loose in the ends of swinging arms 41.

40 is a strengthening rivet connecting the two arms 41 together. The tension device forthe tens of minutes consists of parts 103 and 104 and sprocket 31 loose on short shaft 99,. carried on swinging arms 84, fastened together by a similarlrivet 40 and pulled down by spring 87 fastened to pin 90. The tension wheel of the hours denomination consists of parts 105, 106 and sprocket 31 loose on short shaft 100 supported on swinging arms 85, 85, secured together by rivet 40 and pulled down by spring 88 fastened to pin 91. The tens of hours tension devices consist of parts 107 and 108 loose on short shaft 101 carried in swinging arms 86, 86, lfastened together by rivet 40 and pulled down by spring 89 fastened to pin 92. The swinging. arms are all loose on shaft 42.

Tt will be observed that the records made by my improved machine are always printed in vertical columns and are always preof View. This is adistinct advantage over former elapsed time diagram records 1n the shape of a clock face which are continuallyy shifting and which must be turned around' in order to be read.

The'capacity of my improved machine may, of course, be increased to any extent by increasing the number of recording bands. It is thus capable of indefinite expansion.

27 and 29 are guards for the ink ribbon. To each printing lever is fastened a return spring 35 secured to a rod 36 fast to the frame-work for returning it to its normal position after delivering a printing pressure.

In order to return lever 5 to its home position after being operated, an arm 165 (Fig. 13) is made fast to shaft 11, and to this is secured a return spring 167 secured to the casing ofthe machine at 168.

166 is a stop pin. A similar arrangement is provided for the lever arm 6 on the other side of the case of the machine.v

lMany changes in or modifications from the specific apparatus shown in the drawings may, of course. be made without departing from my invention. Thus it is not essential to my broad invention that bands or endless bands be used to carry vthe type as any suitable device, such as, for example, a cylinder, for supporting or carrymg theyl type may be employed so long as the type are so arranged that when brought past the printing line they will print in a straight line upon the record surface. Again when one part is described as movable with reference to another part, of course, it will be understood that the movement of the second part relative to the rst would be the full equivalent as long as the same result is obtained. y

14:. In an elapsed time recording machine, the'combination of elapsed time recording mechanism consisting of type, representing different units of a denomination of time, arranged so that when brought past the printing line of the machine they will print in a straight line upon a suitable record. surface, an elapsed time indicating mark located upon the recording mechanism opposite the initial unit of the denomination, a printing device adapted on a irst operation of the machine to print upon the record surface in a straight line the type representing units of the denomination and upon a second operation to print upon the record surface the elapsed time indicating mark, and a clock controlled means for moving the printing device with its record surface and the type relatively to each other, whereby the elapsed time between the t-Wo operations of the ma-v chine will be indicated upon the record ferent units of a` denomination of time, ar-

ranged so that when brought past the printing line of themachine they will print in straight lines upon a suitable record surface, an elapsed time indicating mark located on each recording mechanism opposite the initial unit of its denomination, clock-contro-lled means for moving the printing devices with the record surface andthe type relatively to each other, two series of printing hammers, one series opposite the type representing the dierent units of the different denominations of time, the other set vopposite the elapsed time indicating marks, anda separate operating device for each series of printing hammers, whereby when one operating device is actuated the different series of units of the different denominations of time will be printed in straight lines upon the record surface, and when the other operating device is actuated the elapsed time indicating marks will be printed upon the record surface opposite the previously printed lines of units of time.

16. In the recording mechanism of an elapsed time recording machine, an endless flexible band carrying type representing different units of a denomination of time and adapted to move the type in a straight .line past a printing point, two sprocket wheels for supporting said endless band, one a driving sprocket lmounted on a fixed aXle and adapted to be driven by clockwork and the other sprocket loosely supported and a tension device tending to move the loosely mounted sprocket away from vthe other sprocket in order to keep the band taut.

17. In the printing mechanism of an elapsed time recording machine, an elapsed time recording mechanism consisting of type representing different units of a denomination of time arranged so that when brought past the printing line they will print in a straight line upon a suitable record surface, and an elapsed time indicating ,mark located on the recording mechanism opposite the initial unit 'of the denomination.

In testimony whereof, I have signed my name to this specication, in the presence of two subscribing witnesses.
